2. Description of Prior Art

In accordance with the conventional earlier umbrellas, as trying to open, the user has to push the low rib neat sliding up along the stick until get into a proper position, the umbrella is opened, but if running into a passing heavy shower or just only one hand free, the umbrella has been not opened, the user has been drenched. So someone designed an umbrella, in which a button is set upon the handle, as it is pressed down the umbrella is opened automatically, but, without automated-closing function, so that when getting on a vehicle two hands are employed simultaneously for closing the umbrella, even if it will take a short, the user maybe be still drenched by rain, so it is lose its convenient function. Therefore the automated-open-close umbrella was come out, just as the inventor designed and applied patents-an automatic multi-folded or stiff umbrella. By pressing down a button set upon the handle repeatedly, and cooperating with an opening mechanism, a main stick assembly and a ratio mechanism, carry out automated-open umbrella function. Because the handle takes on open and close two functions, so the design of control device in the handle becomes more important.
